Hi,
I'm using gstreamer and DirectFB to create a media player on a ARM11 board.
now I found if i create a surface in my application and pass this surface to
dfbvideosink, it's very slow on my board.and if i let dfbvideosink to create
the surface itself, it's faster.
then i checked the source code in dfbvideosink.c, and found those:
1. in gst_dfbvideosink_setup() it will not get dirctFB initialized if it's
a external surface. just copy some configuation from the ext surface,
2, in gst_dfbvideosink_surface_create() , it will not create any surface is
DirectFB is not initialized,
3, in gst_dfbvideosink_show_frame(), it will check the buffer has surface or
not to decide use Blit or mem_cpy. since using the external surface do not
cause a directfb initialized and then no surface created in buffer. mem_cpy is
chosen. this cause the video playback slower.
I think dfbvideosink should check the external surface support blit or not, if
yes,it should use blit to accelarate.
could you check and fix this?
Best Regards
Joyious
